"The AMD Dual-Core Optimizer can help improve some PC gaming videoperformance by compensating for those applications that bypass theWindows API for timing by directly using the RDTSC (Read Time StampCounter) instruction. Applications that rely on RDTSC do not benefitfrom the logic in the operating system to properly account for theaffect of power management mechanisms on the rate at which a processorcore's Time Stamp Counter (TSC) is incremented. The AMD Dual-CoreOptimizer helps to correct the resulting video performance effects orother incorrect timing effects that these applications may experience ondual-core processor systems, by periodically adjusting the coretime-stamp-counters, so that they are synchronized."
